virtio_net: Use xdp_return_frame to free xdp_frames on destroying vqs



[ Upstream commit 07b344f494ddda9f061b396407c96df8c46c82b5 ]

put_page() can work as a fallback for freeing xdp_frames, but the
appropriate way is to use xdp_return_frame().

Fixes: cac320c8 ("virtio_net: convert to use generic xdp_frame and xdp_return_frame API")
